This paper extends the previous steady-state applications of acceleration signals, which mainly estimate tire force, sideslip, and friction coefficient from the steady-state features of acceleration waveforms, to transient acceleration applications. By using the proposed tire mixed Euler–Lagrange rolling model, it is analytically demonstrated that tire rolling acceleration can be decomposed into steady-state and transient-state components from the perspective of kinematics. It is hard to analyze the transient-state component theoretically or split it from the measured signals on real road surfaces; thus, a learning-based algorithm is developed to automatically extract discriminative features without any physical models. With this method, essential information associated with tire transient acceleration could be inferred to help improve driving safety and performance.\u0000 As the application, tire wear identification with an artificial neural network is validated to be feasible based on complete acceleration signals. The prediction accuracy reaches 98.2% under different test conditions. The proposed acceleration formation mechanism is proved to be effective in explaining tire rolling acceleration as well as guiding to acquire vital information about the tire to improve vehicle safety and performance.","PeriodicalId":44601,"journal":{"name":"Tire Science and Technology","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2021-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45772343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study on the sensitivity of tire behavior to changing its rim width was carried out using the finite element method with the help of Abaqus. For this purpose, the finite element models of a 185/65R14 tire with two rim widths of 5.5″ and 6″ were created and compared in terms of steady-state longitudinal, steady-state lateral, transient longitudinal, and transient lateral behavior, by simulation of stiffness measuring and slip tests. To investigate the effect of rim width on vehicle dynamic performance, several road tests were simulated using a full vehicle dynamic model from CarSim. In each test, at least one of the parameters associated with the discussion of vehicle dynamic performance evaluation including brake distance, understeer gradient, vehicle slip angle, lateral deviation, and roll angle is measured. The vehicle model used is one of the B class instant vehicle models from CarSim, for which this tire size is appropriate. For all subsystems except tires, the same default values were used. For tires, the Pacejka 5.2 tire model is used. Numerical values of the coefficients of this tire model are calculated by fitting the curves of the tire forces and moments obtained from the finite element simulation of required tire tests. The results of the road test simulations have shown that the vehicle with the narrower rim has the better braking ability, but its other behavioral aspects are weaker.","PeriodicalId":44601,"journal":{"name":"Tire Science and Technology","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2021-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41607540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It presents results of further development work on earlier pioneering examples of the application of IGA in pneumatic tire analysis. In addition to the analysis of vertical stiffness, for the first time, velocity and acceleration fields are addressed and compared with experimental results and standard FEA simulations, with a focus on benefits of the continuity of basis functions within the contact patch. The numerical issues that arise in IGA at the enforcement of contact and the application of inelastic materials with inclusions of reinforcing layers are studied.

Around 1970, a group of industry scientists saw a need for a forum for creation of useful tire standards and dissemination of scientific knowledge about tires. This led to the formation of the American Society for Testing and Materials (ASTM) Committee F-09 on tires in 1971. In 1972, the committee began publication of the journal Tire Science & Technology (TSTCA), the first peer-reviewed journal dedicated exclusively to scientific articles on tires. In 1979, ASTM ceased publication of the journal, and in 1980, members of F-09 incorporated The Tire Society to continue publication. In 1982, The Tire Society held its first annual Conference on Tire Science and Technology. Nearly 40 years later, the society has been through many changes, but the journal, the annual conference, and the core mission of encouraging and disseminating knowledge about tire science and technology remain.

HGV tires are designed on a tradeoff between wear resistance, rolling resistance, and adhesion (skid resistance). High wear resistance tires (high mileage) are replaced less often but use more fuel during operation, and vice versa for low rolling resistance tires. Presently, finding the optimal tire to minimize replacement costs and fuel consumption (greenhouse gas emissions) is challenging due to the difficulty in predicting tire wear for a given operation, since its rate varies with different vehicle configurations (e.g., load, vehicle length, number of axles, type of axle, etc.) and road types (e.g., motorways/highways, minor roads, urban roads, etc.).\u0000 This article presents a novel empirical tire-wear model that can be used to predict the wear for multi-axle vehicles based on route data and a vehicle model.

The experimental results were measured from a linear friction tester, while the viscoelastic friction coefficient was estimated using the Persson's contact theory. Adhesive friction (model 1) was derived from the deconvolution of dry friction coefficient in two Gaussian-like curves. Interesting results were obtained using the deconvoluted method in the range of intermediate sliding velocities where preponderant contribution to the adhesion friction is replaced by the viscoelastic friction. Fitting parameter results were in good general agreement with values derived from the literature, confirming the influence of the mechanical properties of the compound and substrate texture on the proposed adhesion frictional method. The second adhesive friction model (model 2) was based on the confinement rheology of rubber chains on the contact with the asperities of the road surface. We demonstrated that acceptable adhesion friction results were achieved from a dynamic viscosity test at low frequencies, confirming the applicability of the proposed rheological model. Moreover, the relationship between the rubber composition and the modified contact layer along with the likely interphase reaction are also discussed.","PeriodicalId":44601,"journal":{"name":"Tire Science and Technology","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2021-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41695997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time, the appearance of smart tire systems will give rise to better tire performance, better vehicle control, and the enhancement of current intelligent systems for autonomous vehicles. In contrast, innovations for the road system, which must carry the increasing traffic loads, have been rare in recent years. However, to solve current and future challenges of mobility related to road transport (e.g., durability, safety, efficiency, ecology, cost, etc.), the potential for innovative trends and digitalization of all interacting components—vehicle, tire, and road—should be used to change the industrial ecosystem and paradigm of transport in human life. The vision of a digital twin of the road system, which is the digital/virtual image (reality model in space and time) of the vehicle, tire, and roadway, would enable, among other aspects, the future pioneering condition predictions of single components (ranging from manufacturing, service to failure state), targeted traffic control, optimal synthesis of building materials and structures, interfaces to automated driving, as well as reduction in emissions. The digital twin of the road system contains and combines all available and relevant information about the “road of the future” system from physical examinations and modeling as well as from data-driven models and further available data (e.g., real-time sensor data from the vehicle, tire and road sensors, data models, etc.).

It consists of several tread blocks with different shape and can be realized by siped structures to improve the traction on the pavement, in particular in wet, icy, or snowy conditions. The blocks are usually made of elastomer materials, which possess viscoelastic behavior. Viscoelasticity can be described by classical rheological models or, alternatively, as shown in this paper, by fractional viscoelastic models. Fractional models can fit the material properties better with fewer parameters.\u0000 Each single tire tread block shows periodically frictional impacts with the pavement. The contact configurations and transitions among stick and slip or impact and detaching can be formulated as a linear complementarity problem, whose solution estimates the local contact forces.\u0000 We simulate transient deformations of a tire tread block by developing a discretized fractional viscoelastic model. The focus is on the deformation process of a tread block with siped structure on different ice tracks with frictional contact. In particular the interlocking of the tread block lips with the edges on the ice surface and the self-contact of the lips are considered. The simulation results are compared to measurements on a high velocity linear testing bench. The contact forces of the frictional contact for plane and rough surfaces on ice and also the deformation process of siped tread blocks, where self-contact can occur, are investigated. The qualitative comparison between results out of simulations and experiments shows a good agreement.","PeriodicalId":44601,"journal":{"name":"Tire Science and Technology","volume":" ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2020-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46157323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
